Ants are fascinating insects, but when they invade your greenhouse , they can cause a number of problems. In this article, we'll explore why these little creatures can be a real challenge for gardeners and how to adopt natural tips to combat their presence.
Why are Ants a Problem in Garden Greenhouse?
Ants can cause several problems in garden greenhouses, including protecting certain pests such as aphids or directly damaging plants by digging galleries in their roots. For example, some species of granivorous ants can attack seeds, reducing germination and development of plants. In addition, the presence of ants can also disrupt the pollination process of flowers, which is detrimental to the production of fruits and vegetables.
Understanding Ant Behavior
There are many species of ants, each with specific behaviors that can harm you after purchasing a garden greenhouse . Granivorous ants feed primarily on seeds, while others prefer the honeydew produced by aphids. Some species are even known to form symbiotic relationships with these pests, offering protection from predators in exchange for the sweet honeydew.
This makes these ants not only harmful to plants but also to the general balance of the vegetable garden. They promote the proliferation of parasites and repel their natural predators such as ladybugs .
Preventing Ant Infestation
To avoid the invasion of ants, it is important to adopt appropriate hygiene and cleaning measures. Here are some tips to prevent their appearance:
Clean the greenhouse regularly: remove plant debris, dead leaves and other potential food sources for ants.
Inspect plants regularly: look for the presence of aphids or other pests that attract ants.
Maintain the surrounding garden: trim hedges and shrubs to prevent ants from accessing the greenhouse.
Spotting the Signs of an Ant Infestation
It is crucial to detect an ant infestation early to prevent it from causing significant damage to plants. Here are some signs to watch for:
Galleries dug in the ground or around the roots of plants.
The presence of small piles of earth near the roots, indicating the construction of a nest.
Lines of ants moving over plants or along greenhouse walls.
If an infestation is detected, acting quickly is essential to limit the damage.
Fight Ants Naturally
Rather than using chemical insecticides, opt for natural methods to keep ants away from your vegetable garden. Here are some solutions and application methods:
Lemon
Lemon is an effective natural ingredient to repel ants without using toxic chemicals. Here are some simple ways to use lemon in your ant control:
Lemon Juice: Mix fresh lemon juice with water in a spray bottle and spray around the greenhouse.
Lemon Zest: Sprinkle dried or fresh lemon zest on ant infested areas.
Apple Cider Vinegar with Lemon: Mix apple cider vinegar, water and lemon juice, then spray the solution on ant trails. This will confuse the pheromones that guide them.
Lemon Peels: Place lemon peels near ant passage areas and not near plants in your greenhouse.
Lemon Essential Oil: Mix a few drops of lemon essential oil with water in a spray bottle and spray the exterior of your greenhouse and walkways.
White Vinegar
Yes, but only around the greenhouse! White vinegar is another effective natural remedy to repel ants. Here are several methods to use white vinegar in your fight against these unwanted insects:
White Vinegar and Water Solution: Mix equal parts white vinegar and water in a spray bottle. Spray this solution on problem areas on the outside of your greenhouse.
White vinegar stains: Wipe surfaces with pure white vinegar or a diluted solution. Ants will avoid areas impregnated with this acidic odor.
White Vinegar Barrier: Create a barrier by pouring a line of white vinegar around ant entry points or infested areas.
White vinegar jars: Place small containers with white vinegar near areas where ants pass.
Essential oils
Essential oils can be effective natural repellents. Here are several ways to use essential oils in your fight against these pests:
Peppermint Essential Oil: Dilute a few drops of peppermint essential oil in water and spray this solution around problem areas or ant entry points. The minty scent will act as an effective repellent.
Tea Tree Oil: Add a few drops of tea tree oil to a clean cloth and wipe down surfaces where ants are found. This can also help remove odor trails that they follow.
Cotton soaked in essential oil: Place cotton pads soaked in essential oil near areas where ants pass.
Lavender Essential Oil: Although less repellent than others, lavender essential oil can be used to mask odors that are attractive to ants.
Coffee Grounds
Coffee grounds are a common kitchen product that can also be used effectively to deter ants. Here are several ways to use coffee grounds in your fight against these insects:
Coffee Grounds Barrier: Place dry coffee grounds along your greenhouse or areas where ants are active. Ants generally avoid crossing these barriers.
Moistened Coffee Grounds: Moisten used coffee grounds with water to form a paste. Place this paste in areas where you have spotted ants. When the coffee grounds dry out, it becomes difficult for ants to cross the area.
Sprinkle Coffee Grounds: Sprinkle used coffee grounds on anthills or in areas where ants are active. This can disturb them and discourage them from settling.
Mix with spices: Mix coffee grounds with spices such as cinnamon or ground cloves. Ants do not like these smells and will be less likely to invade these areas.
Coffee Grounds Repellent: Mix coffee grounds with water and a few drops of peppermint or lemongrass essential oil to create a natural repellent. Spray this mixture on problem areas.
Team note: "Do not sprinkle, spray your plants or mix coffee grounds with your fertilizers, this would only be harmful."
Baking Soda
Baking soda, a common household ingredient, can be used in a variety of ways to deter ants from taking up residence in your home. Here are several ways to use it in your fight against these insects:
Baking Soda Barrier: Sprinkle baking soda around your garden greenhouse.
Mix with sugar: Mix equal parts baking soda and sugar. The ants will be attracted to the sugar, but the baking soda will cause a reaction that will kill them. Place this mixture near the infested areas.
Wet Baking Soda: Mix baking soda with water to create a paste. Place this paste on infested areas.
Repellent: Mix baking soda with water and a few drops of the essential oil mentioned above and spray this mixture on problem areas.
Repellent Plants
There are several natural ant repellent plants that you can incorporate into a polytunnel grow to keep ants away without disrupting the growth of your plants. Here are some ant repellent plants and tips on how to incorporate them:
Peppermint: Peppermint is an ant repellent plant because of its strong odor. Plant it in pots or planters and place them strategically throughout your greenhouse.
Thyme: Thyme is an aromatic herb that can also repel ants. Plant it in containers and position them around your greenhouse.
Lavender: Lavender smells pleasant to humans, but it often repels ants. Plant it in pots or borders.
Rosemary: Rosemary is another herb that can be effective in keeping ants away. Plant it in pots or flower beds.
Chives: Chives are known to repel ants. Plant them in pots or containers and place them around the greenhouse.
To incorporate these repellent plants into your crop without disrupting the crop, here are some tips:
- Use pots or bins to contain the repellent plants. This helps control their growth and allows you to position them strategically around the greenhouse.
- Place pots or bins near potential ant entry areas, such as greenhouse doors and windows.
- Make sure repellent plants get enough light and water to stay healthy.
- Avoid planting repellent plants directly into the greenhouse soil, as this may disturb the roots of other plants.
- Monitor the condition of your repellent plants regularly and replace them if necessary.
